Once a rack passes about 6kW, a 30A circuit is not enough and you start running multiple PDUs and multiple circuits to keep up. A 50A single-phase PDU lets you consolidate. One circuit, one PDU, up to 12kW of rated capacity.
The Valiant Power 50A Single-Phase Metered PDU is built for that kind of load: miners, GPU servers, and dense compute that would eat through a 30A circuit with two or three machines.
12kW rated vs what you should actually run
12kW is 50A times 240V. That is the rating. For equipment that runs continuously, and miners and servers do, code says to plan at 80% of the breaker. On a 50A circuit that is 40A.
| Voltage | Continuous capacity at 40A |
|---|---|
| 208V | about 8,320W |
| 240V | about 9,600W |
Use 9.6kW at 240V as your planning number. That is still enough for two or three current-generation ASIC miners, or several GPU servers, on a single circuit. The built-in meter shows the live load so you know exactly where you are.
Two outlet configurations
| Model | Outlets | Best for |
|---|---|---|
| VP-PDU-50A-V-4913 | 2 x P13, 2 x C13, 2 x C19 | Mining racks with P13 miners plus a controller or switch |
| VP-PDU-50A-V-8313 | 4 x C13, 4 x C19 | Servers, GPU systems, and gear with C14 or C20 inlets |
The P13 version lets newer Antminers with P13 inputs connect directly, while the C13s run your networking gear and the C19s handle anything with a C20 inlet. The C13/C19 version is the more conventional data center layout.
The 6-50P plug
This PDU uses a NEMA 6-50P plug on a 6 foot cord. That is a 50A, 250V straight-blade plug, the same family often used for welders and some EV chargers. You need a 6-50R receptacle on a dedicated 50A circuit. Have a licensed electrician install it, and do not try to adapt it to a dryer or range outlet.

Cables you will likely need
- For C19 outlets feeding C20 inlets: C19 to C20 power cord
- For C13 outlets feeding servers and switches: C13 to C14 power cord
- To split a C19 outlet into two C13 devices: C20 to dual C13 splitter
Frequently asked questions
Can I really run 12kW on it?
12kW is the rated maximum. For loads that run 24/7, plan for about 9.6kW at 240V to stay within code and keep the breaker from tripping.
Does it work on 208V?
Yes. It supports 200, 208, and 240V single phase.
Which version do I need for Antminers?
If your miners have P13 inputs, the version with P13 outlets connects them directly. Otherwise, pick the C13/C19 version.
